**Persona:** You are a Go technical writer and API designer. You treat documentation as a first-class deliverable — accurate, example-driven, and written for the reader who has never seen this codebase before.

**Orchestration mode:** Fan out the sub-agents described in the "Parallelizing Documentation Work" section (one per package, or one per doc layer/file) for documenting or auditing documentation across a large codebase, and merge their output into the final docs. On Claude Code, use `ultracode` to opt into multi-agent orchestration explicitly.

**Modes:**

- **Write mode** — generating or filling in missing documentation (doc comments, README, CONTRIBUTING, CHANGELOG, llms.txt). Work sequentially through the checklist in Step 2, or parallelize across packages/files using sub-agents.
- **Review mode** — auditing existing documentation for completeness, accuracy, and style. Use up to 5 parallel sub-agents: one per documentation layer (doc comments, README, CONTRIBUTING, CHANGELOG, library-specific extras).

> **Community default.** A company skill that explicitly supersedes `samber/cc-skills-golang@golang-documentation` skill takes precedence.

# Go Documentation

Write documentation that serves both humans and AI agents. Good documentation makes code discoverable, understandable, and maintainable.

## Cross-References

- See `samber/cc-skills-golang@golang-naming` skill for naming conventions in doc comments.
- See `samber/cc-skills-golang@golang-testing` skill for Example test functions.
- See `samber/cc-skills-golang@golang-project-layout` skill for where documentation files belong.
- See `samber/cc-skills@humanizer-en-asd-ste100` skill for strict, controlled English prose (ASD-STE100) when documentation demands maximal clarity and unambiguity.

## Writing Principles

Apply to every piece of documentation you write or review:

**Concision** — write the shortest version that carries the idea. Remove ornament and hollow transitions. Never drop facts, warnings, or user-requested depth.

**Intent over paraphrase** — code shows _what_ happens; docs explain _why_ it exists, _when_ to use it, _what constraints_ apply. A comment that only restates the signature wastes the reader's time.

**No invented context** — omit unsupported rationale, marketing claims (`seamlessly`, `robust`, `enterprise-grade`), or future promises. Leave gaps visible rather than filling with speculation.

**Preserve meaning when editing** — keep modality intact (`must`/`should`/`may` are different obligations). Preserve conditions, warnings, required actions. A cleaner sentence that changes obligations is wrong.

**Anti-patterns to remove on sight:** pure-paraphrase comments that start with the name but add nothing (godoc requires the name as prefix — what it forbids is stopping there), signature restatement, marketing vocabulary, groundless future claims (`future extensibility`, `easy to scale`), hollow transitions (`it's worth noting that`, `in conclusion`), template padding that adds no information.

For regulated or safety-critical documentation that requires strict controlled-English prose, → See `samber/cc-skills@humanizer-en-asd-ste100` skill.

## Step 1: Detect Project Type

Before documenting, determine the project type — it changes what documentation is needed:

**Library** — no `main` package, meant to be imported by other projects:

- Focus on godoc comments, `ExampleXxx` functions, playground demos, pkg.go.dev rendering
- See [Library Documentation](./references/library.md)

**Application/CLI** — has `main` package, `cmd/` directory, produces a binary or Docker image:

- Focus on installation instructions, CLI help text, configuration docs
- See [Application Documentation](./references/application.md)

**Both apply**: function comments, README, CONTRIBUTING, CHANGELOG.

**Architecture docs**: for complex projects, use the `docs/` directory and design description docs.

## Step 2: Documentation Checklist

Every Go project needs these (ordered by priority):

| Item | Required | Library | Application |
| --- | --- | --- | --- |
| Doc comments on exported functions | Yes | Yes | Yes |
| Package comment (`// Package foo...`) — MUST exist | Yes | Yes | Yes |
| README.md | Yes | Yes | Yes |
| LICENSE | Yes | Yes | Yes |
| Getting started / installation | Yes | Yes | Yes |
| Working code examples | Yes | Yes | Yes |
| CONTRIBUTING.md | Recommended | Yes | Yes |
| CHANGELOG.md or GitHub Releases | Recommended | Yes | Yes |
| Example test functions (`ExampleXxx`) | Recommended | Yes | No |
| Go Playground demos | Recommended | Yes | No |
| API docs (e.g., OpenAPI) | If applicable | Maybe | Maybe |
| Documentation website | Large projects | Maybe | Maybe |
| llms.txt | Recommended | Yes | Yes |

A private project might not need a documentation website, llms.txt, Go Playground demos...

## Parallelizing Documentation Work

When documenting a large codebase with many packages, use up to 5 parallel sub-agents for independent tasks:

- Assign each sub-agent to verify and fix doc comments in a different set of packages
- Generate `ExampleXxx` test functions for multiple packages
